Is a Thermostat Replacement in Your Future?

Thermostats are an important part of your home’s infrastructure that you may not think much of until they experience an issue. Often, older thermostats are working past their estimated lifespan, and that is when they begin to show signs they may warrant a replacement.

No matter the age of your thermostat, look out for:

  • Inaccurate Readings: The device displays a temperature that doesn’t match the actual air in the room.
  • Unresponsive Interface: The screen stays blank or buttons fail to trigger the air conditioner.
  • Short Cycling: Your HVAC system turns on and off too frequently due to faulty sensor data.
  • High Energy Bills: An outdated controller causes your unit to run longer than necessary.
  • Obsolete Technology: Older manual sliders lack the precision of modern digital controls.

Waqas Shafqat did an excellent job at my house today. He took time to explain to me the steps we needed to take to get my air conditioner to cool properly. I will definitely ask for Waqas next time.

Kalvin was great! He was very professional while explaining future tune ups and code requirements. I believe my present unit is approximately 16 years old and perhaps sometime in the near future best think about replacing the unit altogether. Good information to have, I'll keep Kalvin's recommendation under consideration.

They have been great. I had to have several items attended to on my. HVAC and the original technicians who came were great. Then there was a glitch, so I called the company and they sent Luis out. He fixed the glitch and I am good to go. …No charge.
